Krist - Minable currency that works across servers (paste updated)

Krist is a currency that operates across servers (and in singleplayer). The installer is on the bottom of this post.

Users can send KST to eachother via Krist Addresses, a ten character string that is led by a lowercase k. This is an example of a Krist Address: kg5dc1lzo0

To put KST into circulation, it has to be mined. This involves lots of work done by computers, and means that I can't just "spawn in" as much KST as I want. I have to mine it like everyone else.
Initially, KST was mined by in-game computers, but now requires external software.
